In general, an ASK is a very heavy option.  It sounds relevant in your
case.  Many consistency check options can be much lighter which is
more where my thoughts have been - triggers and enabling object
oriented extensions of the database (in terms of schema validation and
constraints, object oriented data interchange and query, and
server-side object behaviors).

The work on RDF Shapes being done in W3C may be relevant to understanding what consistency checks may be useful for implementing shape validation.
The ABORT mechanism seemed to me to be a small step, fairly easy to implement, and easy to understand what it does. Triggers and OO extensions sounds like more of a learning curve.

I guess also attractive in our case for the ASK is that we already have lots of code that dynamically constructs SPARQL and this would just be more of the same.
